PAPER-FEEDl-NG- MACHINE.

SPECIFICATION forming part of Letters Patent No. 656,524, dated August 21, 1900. Application filed November 14, 1899. Serial No. 736,946. (No model.)

To a/ZZ whom it mag/concern.- v, A

Be it known thatv I, TALBOT C DEXTER, a citizen of the United States, residing at Pearl River, in thefcountyot' Rockland and State of New York, have invented certain new and useful Improvements in Paper-Feeding Machines, of which the following is a specification. i

type, in which the successive sheets of paper in-an automatically-adjustablepile are buckled and separated from the pile andl then fed 0E from the pile to the printing-press, paper-folding machine, ruling-machine, or other machine designed to operate upon the paper. In paper-feeding machines of this type the sheet buckling mechanisms are usually arranged transverse of and above the pile of sheets and are not adjustable horizontally, so that the movement of the bucklingfinger will be directly across the sheet or parallel with the rear edge. In another form of such mechanisms the buckling-finger is horizontally adjustable, but is constructed to oscillate in a curvilinear direction. In bucklin g the corner of a sheet with such mechanisms, however, the sheet naturally buckles in a direction approximating the diagonal of the sheet, so that the movement of the buckling-finger in a transverse direction or a curvilinear direction in a measure restrains the natural buckling movement of the sheet on..

its diagonal, and this straining of the sheet, particularly with large sheets of thinpaper, is liable to rumple and sometimes tear the sheets.

The main object of my present invention is to provide a sheet-buckling mechanism adjustable upon a vertical swivel and having a rectilinearly-reciprocating buckling-finger and a universally-adjustabledriving mechanism, in which the buckiing-.nger will be adjustable horizontally or parallel with the surface ofthe pile of sheets, s o that the mechanism may be adj usted to cause the bucklingfinger to move at any desired horizontal angle with relation to the sheet. With such a mechanism the buckling-finger can be adjusted to reciprocate in the line of natural My invention relates to improvements inA paper-feedin g machinesof the sheet-buckling buckle of the sheet approximating the diagonal.

Afurther object of my present invention is to simplify and improve the general structure of sheet-buckling mechanisms.

Inorderthat my invention may be fully understood, I will firstdescribe the same with referenceto the accompanying drawings and afterward point'out the novelty more particularly in the annexed claims.

In'said drawings, Figure l is a rear elevation of one of a pair of my improved sheetbuckling mechanisms. Fig. l is an enlarged detail sectional view on the linezt ai in Fig. 1. Fig. 2 is an end elevation of same. Fig. is a detail plan view, with parts broken away, illustrating one of the possible adjusted positions of my improved sheet-buckling mechanism. Fig. 4 is a detail sectional view illus- `trating the vertical swivel of one of my sheetbuckling mechanisms.

My improvements are designed for use with a machine of the same general construction as shown in my Patents Nos. 623,769 and 623,770, granted April 25, 1899, and I will only describe in my present case so much ofthe mechanism as will be necessary to a proper understanding of my present invention. f The pile of paper P is designed to be supported upon any suitable construction of vertically-adjustable table, which is not shown, but which is well understood.

-1 is a part of the buckler-supporting frame mounted in any suitable manner upon the main frame of a paper-feeding machine. The

bar 1 is the part of the frame which extends transversely of the pile of sheets.

2 is a bracket adjustably mounted upon the bar l, and 3 4 are upper and lower sections, respectively, of a vertically-adjustable slide which is mounted in guideways in the rear face of the bracket 2 and adjusted to the desired height by means of a screw 5;

The sections 3 and 4 of the slide are formed 95 with ears or lugs 6 7, through which passes a vertical swivel-bolt 8, which adjustably secures the parts 3 and 4 together, so that the part 4 may be adjusted upon the part 3 to any desired angle for the purpose which will 'I oo presently appear. The sheet-bucklin g mechanism is mounted upon the` lower part 4 of the slide. Y

9 is a horizontally-extending plate formed integral with the lower section 4 of the slide and formed upon its rear face with horizontal flanges 10, providing a guideway in which reciprocates the bnckler-carriage 11. The buckler-carriage 1l is in the form of a plate having a vertically-extending bracket-arm 12.

Journaled upon a bolt 13, rigidly mounted in the buckler-carriage 11, is the bucklingnger 14, carryingin its forward end a cylindrical block of rubber 15 and having va heel 16, projecting rearwardly from the journal 13 and carrying an antifriction-roller 17.

18 is alever journaled at 19 to the lower section 4 of the slide and provided with an antifrictionroller 20a for the intermittent engagement of a cam presently referred'to.V

nger, said roller traveling upon said straight edge or face during the reciprocation of the buckler-carriage.

25 is a rod journaled upon a pin 26, secured to the buckling-inger 14 and projected vertically therefrom through the opening in a guide-finger 27, formed integral with the carriage bracket-arm 12.

28 is a spiral spring mounted upon the rod 25 and conned between the guide-nger 27 at its upper end and an adjustable collar 29 at its lower end, the collar 29 being secured to the rod 25. The tension of the spring-rod 25 holds the buckling-linger in engagement With the pile with an effective force to cause the friction-block 15 to engage and buckle a sheet. It will be observed that the bracketarm 12 and buckling finger 14 are both mounted upon and reciprocate with the carriage 1l.

30 is a short rotary shaft journaled in the lower section of the vertically-adjusted slide 3 4, and 31 is a cam keyed to said shaft and adapted to intermittently engage the antifriction-roller 20a, mounted in the lever 18, for the purpose of causing the lever 18 to intermittently raise the buckling-finger away from the sheet against the action of the springdevice just described.

3 5`is a crank-pin, and 36 is a pitman journaled at one end of the crank-pin 35.

37 is a slot formed in the bracket-arm 12, and 38 is a stud adjustably mounted in the slot 37 and having the opposite end of the pitman 36 journaled to it. By the rotation of the crank-pin 35 the carriage is caused to reciprocate Vforward and back in its guideway formed in the lower section of the verticallyadjustable slide. The adjustability of the stud 38 enables the operator `to readily reguthe pile of sheets.

late the operating position of the bucklingfinger upon the pile after the Whole buckling mechanism has been placed into approximately-correctposiiion by the adjustment of the bracket 2 upon the bar 1 and the adjustment of the slide 3 4 in the bracket 2.

40 is a holding-down foot or clamp formed at the forward end of an arm 41, which is journaled upon pin 42, projecting from the forward face of the plate 9. A torsional spring 46, mounted upon pin 42, is adapted to engage the pin 47 on heel 43 of arm 41 for holding the foot or clamp 40 into engagement with The heel 43 projects rearwardly from the journal of the arm 4l, and an antifrction-roller 44 is journaled in said heel and is adapted to be -engaged intermittently by a cam 45, keyed to the short-shaft 30.

As shown in Fig. 3, the sheet-bncklin g mechanism may be adjusted to anydesired horizontal angle to cause the buckling-finger to reciprocate in a direction approximating the natural direction of buckle of a corner of a sheet. The operation will be clear from the above description.

The short rotary shaft 30 is operated by some suitable form of universally-adj ustable operating mechanism. This adjustable 0perating mechanism is preferably in the form of a telescoping shaft the sections of which have universaljoint connections with the short shaft 30 and the driving-shaft of the machine, respectively, such a structure being covered, broadly, by my application filed Sep- IOO tember 21, 1899, Serial No. 731,203, for irnprovements in paper-feeding machines.

48 and 49 represent the tel'escoping sections of the driving-shaft, the ,shaft-section 48 being connected with the short shaft 30 by a universal joint 47, while the shaft-section 49 is connected, through universal-joint connection 51, with a short driving-shaft 52. By the use of this universally-adj ustable drivingshaft it will be clear that the sheet-buckling 'mechanism may be adjusted vertically, transversely, longitudinally, and horizontally with respect to the pile'of sheets Without interfering with the operation of the buckling mechanism..
